SPVM supported self Compiler in 0.9683.

SPVM now supports self-compilers.

What is a self-compiler? It means that SPVM's own source code can be compiled using SPVM.

SPVM has a goal of implementing a browser within 5 years.

The browser downloads the SPVM source code from the web and executes it. In other words, the browser executable generated by SPVM can execute SPVM's source code.

This allows SPVM to be the code of the browser itself, the client code interpreted by the browser, and the code executed on the server side.

This may seem like a distant dream, since browsers require the implementation of a large amount of source code. But the way forward is clear.

Borrow the Web GPU specification, create a rendering engine, and run all applications on top of it. Instead of building applications on top of HTML and CSS, HTML and CSS rendering will be done on top of an engine written in SPVM.

Examples

  use Compiler;

  my $compiler = Compiler->new;

  $compiler->add_module_dir("lib");

  $compiler->set_start_file(__FILE__);

  {
    my $class_name = "Foo";
    $compiler->set_start_line(__LINE__ + 1);
    my $success = $compiler->compile($class_name);
    unless ($success) {
      my $error_messages = $compiler->get_error_messages;
      for my $error_message (@$error_messages) {
        warn "$error_message";
      }
      die "Can't compile the \"$class_name\" class";
    }
  }

  {
    my $class_name = "Bar";
    $compiler->set_start_line(__LINE__ + 1);
    my $success = $compiler->compile($class_name);
    unless ($success) {
      my $error_messages = $compiler->get_error_messages;
      for my $error_message (@$error_messages) {
        warn "$error_message";
      }
      die "Can't compile the \"$class_name\" class";
    }
  }

  my $runtime = $compiler->build_runtime;
  my $env = $runtime->build_env;
  my $stack = $env->build_stack;

SPVM 0.9683 is released.

For Programming Beginners

What Is SPVM?

SPVM is a static typed programming language that can be installed from Perl/CPAN.

How potential dose SPVM have?

Growth is expected in the fields of Bio Tech, AI/ML, Apple/iPhone/iPad Apps, Google/Android Apps, IoT Device, Connected Car, Smart Device, Smart Home, etc.

This is because SPVM can produce an executable file that supports cross platforms and make easy to calculate arrays and bind C/C++
